There isn't anyone inside this six-and-half-ton beast, getting off on smashing through crappy 80s cars. No, the Army's latest baby, built by Carnegie Mellon's Robotics Engineering Center, is a robot. The Crusher navigates (and destroys) autonomously and will climb four-foot "steps" as easy as it tears up a hill. Apparently other vehicles in their Future Combat System family will take after this big bad monster truck, officially bringing the Army into the business of wrecking ass. With robots.
